95 skylark starting issues - please help!

I'm having trouble starting my 95 skylark. Both the starter and battery have tested fine at Advance Auto. The starter clicks when turning the ignition and that's all. I replaced a couple wires that looked questionable including the positive battery cable. Using a multimeter, the battery shows 12V. I also replaced the coil pack. What else could I try before taking the car to a mechanic?

Thanks!

I had my 95 Skylark a week when this happened to me. It clicked and wouldn't start. I'd charge the battery and the car would work temporarily. After replacing the battery I still had the problem. I needed a new alternator and a new battery.
